This is the third post that you have created asking questions about other themes... This section is meant for the discussion of the development of new a theme. These are ok questions to have. They ultimately help nothing, as they are after thoughts. We would like to focus on discussion that assists with development.

Second no announcement has been made on when a new theme will be released meaning there is not really a version tied to it yet, which means again until we have a new theme none of this can really be answered or should.

however to venture an educated guess since the name of the theme is [color=FF0000]prosilver[/color] SE it will probably stick around as a community theme as long as prosilver is around

Moved to a different forum. prosilver SE is not part of the standard phpBB package. Please read the topic titled Purpose of this forum before making any additional topics in the style development forum.
